`AUTOMOBILE HEADLIGHT. 1

Application 1aed January e, 1927. serial No. 159,324.

My said invention relates to headlights for automobiles or other vehicles and it is an object of the invention to provide a headlight capable of illuminatingthe roadway both ahead of and to the sides of a vehicle upon which the same is mounted without glaring or blinding the eyes of the driver of an approaching vehicle or the eyes of a person looking directly at such light.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference Characters indicate similar parts,

Figure 1 is a central longitudinal vertical section,

Figure 2, a fragmentary section taken on line 2 2 of Figure 1, i

Figure 3, a modified form of reflector.

In the drawings reference character 10 indicates a casing or shell having a hollow support 11 for attachment to a part of the vehicle and by means of which the headlight is adapted to be supported. A socket 12 is mounted on the casinglO and such socket is provided with conductors 13 which extend to a light bulb 14. If preferred the conductors 13 may be inserted through the `support 11 instead of as shown. The casing or shell 10 is preferably parabolic in form and the reflector 15 is o-f conical shape and is adapted to be mounted within the same, such reflector being provided with an annular flange v16 which engages the end of the casing. The casing or shell 10 is provided with an overhanging shell 17 which is of substantially the same depth as the casing 10 but covers substantially only the upper half of the lamp, the lower half of which is provided with a lens 18 of transparent material which permits light to bev reflected therethrough. The overhanging shell is provided with an inwardly extending flange 19 lwhich supports an external flange 2O on the lens 18. The casing 10 is provided with 'a plurality of forwardly extending fastening elements or lingers 21, one being disposed preferably at each side and one at the top of the same, and through which fastening screws 22 extend into the casing 17 for securing said casing and the lens in position. A substantially parabolic reflector 23 is mounted in the overlianging casing 17, such reflector being provided with an'aperture at itscentral portion in which is'mounted the cylindrical part of the lamp or bulb 14 adapted to be clamped in position by means of a set screw 24. As will be observed from Fig. l the reHector 23 is so arranged as to project the light upon the conical reflector l5 from whence it will be reflected through the forward, side, and bottom portions of the lens 18. On account of the particular manner of mounting Vthe light 14 within the reflector 23 it may be moved toward and from the conical reflector 15 and in order to vary the inclination of the reflector 23 l preferably mount the same on a yoke 25 which has one end mounted in a bracket 26 at one side of the overhanging shell 17 while its opposite end projects through the opposite end of said shell and is provided with a knurled operating knob 26. Also a lock nut 27 is provided f-or locking the yoke 25 and reflector carried thereby in the proper adjusted position. By means of this yoke the reflector and light may be swung about the aXis of the yoke and the angle at which the light shines upon the reflector will be varied accordingly. ln lieu of the parabolic reflector 23 shown in Fig. 1 a conical reflector 28, such as shown in Fig. 3, may be used.

VIf desired the forward section of my light may be applied to a conventional headlight with or without the substitution of a conical -reflector, however, I have found it advantageous to use a conical reflector as l have shown. With the structure illustrated the light from the bulb 14 will shine directly on the conical member 15 and willbe reflected onto such reflector by the parabolic reflector 23 and from such a conical reflector the light will be projected ahead through the lens 18 below flange 19 and downwardly on the roadway and on the adjacent territory at the sides of the roadway.

With the foregoing device light will not shine above a horizontal plane so that it will blind the eyes of a driver of an approaching vehicle or other person looking directly at the same but will efliciently perform the function for which is is designed.

It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of my invention and therefore l do not limit myself to what is shown in the drawings and described in the specification but only as indicated in the appended claims.

Having thus fully described my said invention, what l claim as new and desire to secure by Letters Patent, is:

1. A headlight comprising an elongated oval-shaped casing, a transparent lens forming substantially one-fourth of said casing at the lower forward portion of the same, a

Y conical refiector mounted opposite said lens in a position to project light through said lens, an auxiliary reflector mounted above said lens in opposed relation to said conical reflector, and a source of light in said auxiliary reflector' adapted to have its rays projected onto the conical reflector and through the lens, said auxiliary reflector being pivot allyV supported on a transversely disposed pivot whereby the same may be swung about the same, substantially as set forth. Y

'2. A headlight'comprising an Velongated oval-shaped casing having a curved detachable overhanging forward vhalf-section, a lens for said headlight, said overhanging half-section and said lens beingr complement-arily formed and curved in conformity with the casing, aV conical reflector mounted Within said casing, a source of light in said casing, a yoke journalled in the sides of said overhanging half-section, and a refiector carried by said yokewhereby the same may be adjusted above the horizontal axis of the Y conical reflector7 substantially as set forth.

In Witness whereof, I have hereunto set my hand at Indianapolis, Indiana Vthis 4th day of January, A. D, nineteen hundred and twentyseven.
